  • Do plasticizers soften thermomechanical properties?
  • The effect of the different single-component plasticizers (glycerol, propylene carbonate and ethylene carbonate) on the mechanical and dynamic thermomechanical properties of the films were studied. Moreover, the softening effect of the two-component plasticizer based on deep eutectic solvents (DESs) was addressed.
  • How do plasticizers affect the mechanical properties of a polymer film?
  • The addition of plasticizers affects the mechanical properties and WVP of a polymer film by altering the intermolecular interaction of polymer; also, the added plasticizers alter the moisture sorption behavior of resulting films which is an important factor in deciding the stability of edible film/coating.
  • How do plasticizers affect tensile strength?
  • In general, yield and tensile strength of PLA decreased, and fractured strain increased with the addition of plasticizers. Further increments in elongation at break obtained as plasticizer content increased. Over time, the tensile modulus increased and the elongation at break decreased in all plasticized PLA blends.
  • Do plasticizers change tensile properties after 1 year?
  • Figures 7 and 8 show that yield strength and E-Modulus of the plasticized PLA increased and EAB (Fig. 9) dramatically decreased at any given plasticizer type and loading level after 1 year from production. All of the changes in tensile properties after 1 year resulted from the migration of the plasticizers to the PLA surface.
  • Why do plasticizers decrease the strength of polymeric materials?
  • Generally, a decrease in the strength of polymeric materials is common when plasticizers are added because of the weaker interaction between polymeric chains (Sanyang et al., 2015) (Fig. 1).
  • Why is plasticizer important for biopolymer film preparation?
  • Apart from polymer and solvent, the plasticizer is the other important ingredient for the preparation of biopolymer film in order to enhance the flexibility of polymers by reducing the glass transition temperature (Tg). Water is not only the most common solvent but it also acts as a plasticizer for natural biopolymer films.
